` 1s claims. (ci. 51-164) This invention relates to improvements in Tumbling barrels.

'The main objects oi this inventori are:

First, to provide an improved tumbling barrel which is well adaptedfor the practice of wet nishing methods in that it is fluid-tight and at the same time is comparatively simple and economical in structure.

Second, to provide a tumbling barrel whereby the worn out wood lining can be removed and replaced without expending labor for removing the cylinder from the machine and the heads from the cylinder.

Third, to provide a tumbling barrel having permanently associated metal ends instead of removable ends, bulkheads, and wall panels' which can be readily lined without knocking down the machine. l

Fourth, to provide a tumbling barrel in which the lining is mainly made up of strips or bars of wood positioned so as to effectively withstand the wear.

Fifth, to provide a lined tumbling barrel in which the liner elements are supported Without the necessity for bolting to the walls of the barrel.

The embodiment of my invention illustrated comprises metal polygonal end members I provided with journals 2. The supporting frame and bearings for these journals are not illus- Objects relating to details and economies of the invention will appear from the description to follow. The invention is dened in the claims. A preferred embodiment of the invention is illustrated in the accompanying drawing, in

trated. The structure illustrated is an octagonal structure and structures having an even number of sides have certain advantages which will appear as the description proceeds.

The polygonal sheet metal wall member 3 is welded to the end members. This wall member .comprises angularly disposed panelsthere being one less panel than there are sides to the barrel. The structure illustrated is a two-compartment structure and is provided with an intermediate partition or bulkhead 4 to which the side panels are welded, the bulkhead constituting a supporting and reinforcing means for the wall panels, permitting the use of lighter gauge stock than would be required in tumbling barrels of the same length having only one compartment.

As stated, the wall member has one less panel than there are sides to the barrel and I provide a complemental Wall panel comprising a frame 5 welded to the adjacent edge of the terminal panels 6 of the wall member 3 and to the end members and bulkhead. It will be noted that this frame is of such proportions as to constitute laterally projecting flanges on the panel 6 and on the end members. In the structure illustrated the frame has two openings 'i'.

The panel plates 8 are detachably secured to the frame by means of screws 9. The wall panel ill opposite the panel constituted by the wall panel plates is .provided with` door openings ,I I, the detachable doors being shown at I2, door clamping means I3 being detachably secured by means of bolts Iii.

The end walls and bulkhead are provided with liners I5, these liners being arranged against the sides of the end panels and bulkhead and preferably being made up of sections as indicated in Fig. 2.

The side walls are provided with lateral units I6 preferably made up of a series oi.' bars Il arranged in side by side relation and retained in assembled relation by dowels It. These panel liners have mitered edges I9 adapted to abut when they are in assembled position.

The panel having the door opening therein is provided with frame-like liner members 2U surrounding the door opening and.' the doors are provided with liners 2l iitting into these framelike liner` members. These" frame-like liner members constitute abutments for the adjacent panel liners I6. see Fig. 2;

The removable wall panel plates 8 are provided with liner-panels 22 corresponding to the liner panels I6, these being in mitered engagement with adjacent panels and in effect constituting a key-stone element securing them all in position. The liner panels may be temporarily supported in place as, for example, by means of a prop until the assembly is complete.

The opening 1 in the frame 5 is of such dimensions as to permit the introduction of the liner units I 6 in assembled relation. When introduced, the strips or bars I1 forming the liner units are spaced apart or there is suflcient slack in the assembly on the dowels so that when they become expanded or swollen they form a relatively tight continuous surface.

By thus forming these liner panels the grain of the wood is presented so that it is subject to the least amount of abrasive Wear-that is, the tumbled material moves across the same in the direction of the grain and is much less likely to tear the grain and wear down the liner vthan it would where the movement of the material is crosswise of the grain. The doors counterbalance the-frame and the panel plates.

My improved. tumbling barrel can be made of relatively light stock and at the same time is `strong and rigid and very durable. The body of the barrel may be formed complete and the liners readily introduced which is of substantial manufacturing advantage and also a very great advantage to the user because it makes it possible for him to re-line th'e barrel as the liners may become worn.

I have illustrated and described my invention in a very practical embodiment thereof. I have not attempted to illustrate or describe various modifications and adaptations which I contemplate as it is believed that this disclosure wil1 en able those skilled in the art to embody or adapt my invention as may be desired.
